I stayed for one month and I can say confidently that it was the best one in Onnut area.
Location was great within walking distance from BTS Onnut station. Two supermakets and local market nearby perfect for groceries. There are lots of nice restaurants nearby also.
The condo is newly built one and amenities and equipment was new and clean. The gym and swimming pool was well managed and enough to work out.
The host Alex, is a nice person. He showed up in person during the check-in procedure and explained almost everything in detail.
Highly recommend to single/ couple travellers who is interested in the local life in Bangkok.
It was quite an impressive stay and I decided to extend my stay in Bangkok for another month and booked to another condo out of Alex's listings.
